Serrapeptase by Doctor's Best contains 40,000 SPU of the protein-splitting enzyme serrapeptase from the Serratia bacterium, strain E-15. Thanks to the Serrateric™ coating, the enzymes are only released in the intestines and not in the stomach. One to three capsules a day, without food. Vegan.

Five thousand years of silk

The silkworm (Bombyx mori) has been bred for thousands of years; according to Chinese tradition, Empress Leizu discovered silk when a cocoon fell into her tea. To get out of the cocoon, the moth uses an enzyme from a bacterium in its gut. That enzyme is serrapeptase.

Made in the United States

Doctor's Best has the capsules made in the United States. The serrapeptase is protected with Serrateric™, a coating based on calcium salts. The capsule is plant-based and the product is vegan.

Facts about this product

One capsule contains 40,000 SPU serrapeptase. Take one to three capsules a day without food. Doctor's Best recommends starting with this dosage before you use the stronger 120,000 SPU.

Serrapeptase 40,000 SPU by Doctor's Best

Serrapeptase is a proteolytic, or protein-splitting, enzyme derived from the Serratia bacteria strain E-15. Serrapeptase is also known as serratiopeptidase, serrapeptidase or Serratia E-15 protease. This variant of Doctor's Best Serrapeptase contains 40,000 SPU. This product is also available in 120,000 SPU.

Enzymes are released only in the intestines

These serrapeptase capsules come with a Serrateric™ coating. This is a superior alternative to enteric coated capsules. The unique coating ensures the enzymes are released strictly in the intestines and not in the stomach. Stomach acid can destroy serrapeptase. The enzymes are optimally absorbed in the intestines. The enzyme serrapeptase splits proteins and is active in the mucous membranes, among other places.

Benefits

Proteolytic, protein-splitting enzyme from Serratia bacterial strain E-15. Serrateric™ coating ensuring the enzymes are optimally absorbed through the intestines. Does not contain gluten; GMO-free. Suitable for vegans and vegetarians.

Japanese silkworm

This proteolytic enzyme is present in the intestinal bacteria of the Japanese silkworm. Serrapeptase is used by the silkworm to dissolve the cocoon. As a supplement, it has been on the Asian and European markets for decades and has been well researched for 40 years.

Quantum effects of enzymes

Enzymes do essential work throughout our body. They are catalysts for biochemical reactions inside cells and can accelerate these processes up to a trillion times. How does this work? Enzymes make use of what in quantum mechanics is called the tunneling effect. A particle passes through a barrier. Imagine it like this: the particle doesn't have enough energy to go over a high mountain, but it can teleport itself through a kind of tunnel. It disappears on one side of the mountain and reappears on the other side at the same time. Without tunneling, enzymes would never be able to accelerate chemical reactions to the extent that they do.

08 / Frequently asked questions

What you still wanted to know.

Only in consultation with your doctor. Serrapeptase, nattokinase and lumbrokinase are protein-splitting enzymes; Doctor's Best advises against use alongside blood thinners, or only under medical supervision. Also with a bleeding disorder, during pregnancy and around surgery: consult first, and stop well before a planned procedure.

Digestive Enzymes contains 15 enzymes for carbohydrates, proteins and fats and you take it with every meal. Gluten Enzymes contains only protein-splitting enzymes, aimed at gluten proteins. Proteolytic Enzymes is a high dose of protein-splitting enzymes, including serrapeptase, which you take precisely without food. Betaine HCl & Pepsin contains no plant enzymes, but betaine HCl and pepsin.

A protein-digesting enzyme from the bacterium Serratia (strain E-15), originally found in the gut of the silkworm. Each capsule contains 40,000 SPU.

Serrateric™ coats the enzyme so that it is released only after the stomach. The coating contains calcium, so each capsule also provides 27 mg calcium.

One capsule, one to three times a day, without food, or as advised by your doctor. At one a day, a jar of 90 capsules lasts three months. The product is vegan.
